A gasket with no gaps.
One continuous loop of silicone sits in a channel around the lid. When the latches close, it compresses evenly — no corners for air or moisture to sneak through.






















Two extra-large keepers with a continuous silicone seal, wide flip-latches, 250ml measuring cups and reusable chalkboard labels. Sized for whole bulk bags.
Why it works
Scroll through the parts that keep air, moisture and pests out — and make the keeper a pleasure to use every day.

One continuous loop of silicone sits in a channel around the lid. When the latches close, it compresses evenly — no corners for air or moisture to sneak through.
Food-grade SAN gives a glass-like view of what's inside, without glass weight or fragility. It resists stains and odours, and goes in the dishwasher.
Two wide flip-latches press the lid down along its full length, so the seal is even every time — and it opens just as easily when your hands are full of flour.
A 250ml measuring cup lives inside each keeper and the 17.5 cm mouth fits it with ease. Chalkboard labels wipe clean when you switch staples.
What fits in 8.5L
Measured capacity per keeper. Pour the whole bag in — no half-empty sacks rolled up with rubber bands.

One footprint across the collection, so every keeper lines up and stacks on the shelf.
